Abstract

We propose a concept of self-enforcing risk-sharing agreement that are robust not only to single-person deviations but also to potential deviations by subgroups, requiring that the deviating subgroup itself employs some self-enforcing risk-sharing agreement. We observe that the stability of subgroups may destabilize insurance arrangements among larger groups. Using this concept of stability, we study different examples.
